Question

If 4 is a zero of the cubic polynomial x3 – 3x2 – 10x + 24, find its other two zeroes​

Answer 1

Answer:

$x {}^{3} - 3x {}^{2} - 10x + 24 \\ (4) {}^{3} - 3(4) {}^{2} - 10(4)+ 24 \\ 64 - 3 \times 16 - 40 + 24 \\ 64 - 48 - 40 + 24 \\ 16 - 40 + 24 \\ 16 - 16 = 0$

ans is zero

Answer 2

Answer:

2, -3

Step-by-step explanation:

Polynomial ⇒x  

3

−3x  

2

−10x+24

4 is a zero of polynomial so (x−4) will be a factor

+3x−2x−6=0

x(x+3)−2(x+3)=0

(x−2)(x+3)=0

x=2,−3

Other two roots ⇒2,−3
